Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Assessment of Post-Harvest Technology and Rice Farmers Income in Ekiti State
Full text linkA major problem with the domestic output of rice in Nigeria is the poor operational techniques of processors which often aids low production. Efforts of government through the agricultural development project (ADP) to improve rice processing especially in Ekiti state have proven ineffective. The study therefore, examines the assessment of post-harvest technology of rice in ekiti state. The study makes use of 80 respondents’ farmers and processors in Igbemo-ekiti, using a purposive, snowball and random sampling techniques. The data collected from the study were analyzed using the frequency and percentage tables and budgetary technique. The study reveals that male respondents constitute 55% with 71.3% no of year spent in school and majorities (75%) of the respondents are within the economically active age that favour processing activities. Meanwhile, the adopted processing technologies in the study area are primitive ones and modern processing technology is most profitable with gross margin of ₦9,850 and ₦1.34k as return on investment. Much earning flows in with the use of modern technology; thus, there should be an effort of private bodies, government, farmers and processors to increase output through the use of various modern technologies.

A Methodology for Measuring the Property Flood Resilience (PFR) of Households at the Risk of Flooding
Full text linkThe risks of flooding have been ever present for homes located in flood plains or close to coastal areas. Surface water flooding and flash flooding in urban areas means that homes located away from flood plains and coastal areas may also be exposed to flooding. While some of these homes have developed a level of resilience over time, many have very poor, inadequate or lack any level of resilience to flooding. This raises the questions as to what level of resilience is appropriate; how best to quantify flood resilience at the level of the individual homes; and what steps to take to improve resilience. However, despite the current focus on resilience within UK flood risk management policy and strategy, no accepted definition for the term exists and, more significantly, there is a lack of a general measurement framework for determining the level of flood resilience for an individual home. Hence, the aim of this research is to develop a model for reliably measuring the level of resilience present in individual homes at risk of flooding.
In order to establish the framework for this research, a comprehensive literature review was conducted on the concept of resilience and flood risk management in the context of households. Based on a synthesis of the literature, a conceptual framework of Property Flood Resilience (PFR) at the household level was developed which comprises both building and human components. A quantitative research methodology was employed towards testing the design and validity of the PFR framework, with data collected through a questionnaire survey of homeowners who have experienced flood events on their properties.
Different sets of analyses were performed on the data collected, including the normality test, analysis of variance (ANOVA), correlation analysis, and regression analysis. The overall PFR was modelled with the building and human resilience using multiple linear regression, and from this model it can be inferred that building and human resilience significantly predicts the level of the overall PFR. Further, building resilience were found to be positively and significantly associated with human resilience (at r = 0.407). This implies that increases in the resilience of the building component will result in an increase in the human resilience and ultimately increase in the overall resilience of the individual household.
The PFR model developed provides valuable information on the flood resilience levels currently present in the home for the benefit of homeowners. It also provides property experts and surveyors with a tool to estimate resilience levels within a property, enabling them to provide impartial and professional advice on risk exposure and measures that can be adopted to help further protect properties. The model also serves as an evidence based tool to inform insurers on the levels of resilience present within a given property and to consider how this might affect insurance premiums and excesses which will in turn improve the role of flood insurance as a market-based incentive, and to complement Government‘s effort in encouraging homeowners to invest in PFR
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
